IMPROVEMENT IN GRAIN-SCOURERS.

Specification forming part of Letters Patent No. 130,315, dated August 6, 1872.

To whom it may concern:

Be it known that I, DAVID M. RICHARDSON, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Machines for Cleaning and Scouring Wheat; and I do declare that the following is a true and accurate description thereof, reference beinghad to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure 1 is an elevation of the bevel side of one of the spiders shown in the patent issued to Ephraim Russell, February 14, 1871, with my improved teeth applied thereto. Fig 2 is a crosssection through the line as x in Fig. 1, and Fig. 3 is a perspective view of a portion of one of the arms.

Like letters indicate like parts in eachfigure.

The nature of this invention relates to an improvement in the construction of the machine for cleaning and scouring wheat patented by Ephraim Russell, February 14, 1871; and has for its object the more effectual removing from the wheatberries of the fuzz and chit at the ends thereof than can be accomplished by the said machine. The invention with the exception of the teeth therein referred to, which I replace by the small segments a a, disposed on the blades-of the arms, as shown in Fig. 1 in the accompanying drawing.

It is found in practice that while the machine patented by the said Russell effectually scours the wheatberries, in their passage through the machine, it fails to remove the fine fuzz and chit growing in the end of the berry, and in which the smut-germs gather. The arms fitted with my improvement first catch the berries on the inner faces of the segments a, whence they are deflected and strike endwise upon the segments a, and in the concussion the ends of the berries are sufliciently bruised to liberate the fuzz and chit referred to without breaking. The berries pass along between the ends of the segments a, the sides of the segments a, and strike against the segments to succeeding, when any adhering fuzz or chit is beaten off the berries, and are then turned end for end before coming in contact with the succeeding segments a, which effectually complete the process.

What I claim as my invention, and desire to secure by Letters Patent, is-- The spider A provided with the curved segments at a, arranged as described, for the purpose set forth.
